  • Configuring VLAN Priority on Core Switches

    Configuring VLAN Priority on Core Switches

    With Per VLAN Spanning Tree (PVST) we configure a specific switch to become the root bridge for each VLAN. You can do this with the spanning-tree vlan X root primary command which sets the priority automatically, or you can set the priority manually with the spanning-tree vlan X priority command. A Virtual Local Area Network (VLAN) is a logical grouping that segments a network into smaller broadcast domains. VLANs allow you to separate network devices into distinct groups, even if those devices connect to the same physical switch or to different switches. All vlans exisit on all switches. The root bridge is the elected reference point from which all spanning tree paths are calculated. The vlan command in global configuration mode creates a new VLAN and updates an existing VLAN.

  • Does an all-optical network include switches

    Does an all-optical network include switches

    This means that random signal storage, transmission, and switching are all handled in the optical domain. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices. This tutorial covers the all-optical switches themselves – the various types, how they differ from electronic switches, where they sit in networks, what functions they perform, how they're controlled, and what they can and can't do.

  • Aggregation Switches and Environment

    Aggregation Switches and Environment

    Switch aggregation is transforming how networks handle data traffic. By combining multiple switches into a cohesive system, organizations can improve efficiency, scalability, and management. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. An aggregate switch is a high-capacity network switch that consolidates connections from multiple access switches, acting as a central point for managing network traffic and providing enhanced bandwidth capabilities. This article looks at what each such tool does, compares how they differ from each other, and offers suggestions as to what sort of network each. Switch aggregation, also known as link aggregation or trunking, is a method used in computer networking to combine (aggregate) multiple network connections in parallel. Understanding the.
